Dentures loose, a medical episode or just dry mouth: what was going on with President Trump's Jerusalem speech? Watch the video and decide for yourself.

UpdatedUpdated 8 December 2017

The White House has hosed down speculation over President Trump's odd delivery of a speech announcing the US would recognise Jerusalem as Israel's capital, saying it was just a case of "dry mouth".

But following the incident, which raised concerns about the President's health, the White House announced the President has scheduled a medical checkup for early next year and will share the results publicly.

Social media erupted over Wednesday's speech, in which the President appeared to be breathing heavily and slurring his words, garbling the traditional sign off "God bless the United Shtates".

Some viewers speculated the president was having a medical episode, was losing his dentures, or was under the influence of drugs.

Some also compared his signature made on an executive order following the speech with earlier signatures, with one Twitter user suggesting "something serious is going on".

Trump slurs his words. Walks out of the room confused, forgetting to sign an executive order. Compare the recent signature (left) with one from a previous executive order (right). Something serious is going on and the American people have a right to know. pic.twitter.com/KrUXdkOFqH

After watching the video - Professor de Riesthal has never treated the President - he said "There was definitely some imprecise progressive change in articulatory precision and slowing of his speech that is not typical in normal speech. The distortion of his articulation, though, is unknown in etiology".
